This is a minor rant, since I'm at home this Monday on a holiday, so I'm less irritated by life in general than I normally am on a Monday.
In marking hordes of undergraduate formal lab reports, one thing that gets fucked up on a regular basis is any graph. For some reason, the repetitive lessons everyone gets in junior high school, high school, and intro-level science courses about appropriate labels and axes in graphs are easy to forget. Look, you're supposed to pay attention to the axes labels on a graph because that's how you know some slimy marketer-type is lying to you.
This concept must be foreign to both the hordes of SFU undergrads and MicroSoft's software engineers, given the default (shitty) settings of MS Excel.
You MUST label your graph axes.
You MUST include a numerical scale
You MUST make the scale make sense - drop the 120% mark on your "percent survival" curve!
If your numbers are all much closer together than any is to zero, you have to either use a ridiculously long vertical axis, or include a visible break line.
These are not difficult rules - so why do I see so many Watson-damned broken figures?
